Application October 13,

3 Claims.

This invention relates to a shoe heel construction and more particularly to a fastening means for detachably connecting a heel to a shoe upper or for detachably securing one section of a shoe heel to a companion section, so that when it is necessary to replace a section or a heel in entirety due to damage or wear the replacing may be easily and quickly carried out by anyone unskilled in the art and without the use of shoemakers tools.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

' For a complete understanding of my invention, reference is to be had to the following description and. accompanying drawings, in which Figure 1 is a side elevation illustrating a shoe heel construction made in accordance with the present invention and showing the application plate of the fastener secured on a removable part of the heel construction.

Figure 4 is a vertical sectional view showing the heel assembled and secured together by fastening means in accordance with the present invention.

Figure 5 is a sectional view taken on the line 5-5 of Figure 2.

Figure 6 is an exploded perspective view illustrating the removable section of the heel construction with a part of the fastening means secured thereto.

Figure 7 is a perspective view illustrating one section of the heel carried by the shoe upper with one of the plates of the fastening means secured thereto.

Figure 8 is a sectional view taken on the line 8-8 of Figure 4.

Figure 9 is a side elevation, partly in section, illustrating the fastening means employed for securing a shoe heel to a shoe upper Figure 10 is a perspective view illustrating the shoe heel detached from the upper. I

Figure 11 is a perspective view illustrating a fragmentary portion of the shoe upper with one of the plates of the fastening means secured thereto.

As will be seen by referring to the various 1939, Serial Nb. 299,356

views of the drawings the present invention is readily adaptable to mens and ladies shoes and consists of a relatively fixed plate 5 secured in place by screws or like fasteners 6 and has struck therefrom a series of keepers I. A removable plate I is shaped to match the general outline of the plate 5 and has struck therefrom a plurality of hook-shaped elements Ill to engage with the keepers l. The hook-shaped elements In may be readily moved into and out of the keepers I by moving the removable plate 8 endwise of the relatively fixed plate; The plates 5 and 8 have openings which are adapted to align when said plates are assembled together for the purpose of permitting a spring influenced pin ii to extend through both plates and thereby secure said plates against endwise movement relative to each other and which will prevent the hook-shaped elements ill from moving out of the keepers 1.- The pin H is slidably mounted in a casing I2 formed on or secured in any suitable way to the relatively fixed plateas shown in one form of the present invention, while in the other form of the invention it may be carried by the removable plate. A coil spring l3 acts on the pin II to retain the pin extended through the openings of the plates 5 and 8. To bring about separation of the plates it is necessary that the pin be pressed out of the opening of one of the plates, as for instance, out of the opening of the plate 8 so that said plate may be moved relative to the plate '5 for disengaging the elements ill from the keepers 1 to permit separation of the plates.

To adapt the present invention to a heel of a man's shoe as shown in Figures 1 to 8, inclusive, of the drawings, the heel construction which forms a permanent part of the shoe upper is designated by the character It and has the plate 5 secured thereto by the fasteners 6. The tread or removable part of the heel is indicated by the character l5 and has the plate 8 secured thereto. The section l5 of the heel is preferably chambered to receive the plate 8. The section l5 of the heel may be constructed of rubber or any other material suitable to form the tread or wear-receiving portion of the heel construction and may be composed of front and rear sections A and B. It is well known that the tread section l5 of the heel construction usually wears quicker at the rear and side edges thereof than any other portion and by having the sections A and B as specified the section B when worn may be easily removed and replaced by a similar section. When employing the sections A and B with the section I! of the heel construction the plate 8 may be III heel construction of a man's shoe the section ll is provided with a chamber or recess i9 to receive the casing l2 and a part of the pin ll, while the other section it has an opening 28 extending entirely therethrough and aligning with the opening in the plate 8. A screw 2i is mounted in the open. ing 20 by being threaded into a nut 22 confined in the opening 28 for the purpose of moving the pin I i out of the opening of the plate 8 when desiring to disconnect the sections i5 and ll of the heel construction.

To prevent dirt and other foreign matter from entering the opening 20 during normal use of the shoe heel, a removable lug 23 may be employed for closing the opening and thereby preventing the screw 2i from being affected by the entrance of dirt and the like in the opening 20.

Should it not be desired to employ the screw 2i for operating the pin, a pointed instrument of any kind may be employed for exerting endwlse movement to the pin ll suflicient to disengage the latter from the plate 8.

While the foregoing description is believed to clearly explain the use of the present invention to a shoe heel employed upon mens shoes, it will be understood that the application of the present invention may be readily carried out ona ladys shoe as shown in Figures 9 to 11, inclusive, and when adapted to this type of shoe, the plate 5 is secured to the shoe upper 24 and may be provided with an extension strip 25 extending into the arch of the shoe upper for the purpose of reinforcing the arch. The plate 8 is secured on the shoe heel 28 within a recess provided in the shoe heel. In this instance, the plate 8 carries the casing l2 and the latter is shown seated within a chamber or recess 29' formed in the heel 28. The shoe upper 24 directly above the opening in the plate 5 has a small opening 29 to permit an instrument to be brought into engagement with the pin II when desiring to move the pin out of the opening of the'plate 5 to bring about the separation of the heel from the shoe upper.

It is believed that the simplicity and advantages of this invention will be apparent to those skilled in the art to which such a device relates, and while I have herein set forth a. satisfactory embodiment of the invention, it is to be understoodthat certain changes therefrom as fairly fall within the scope of my claims may be resorted to s when desired.

Having described the invention, what I claim is: 1. A fastener for the assembly of a shoe heel comprising matched plates, keepers formed on one of said plates, locking elements formed on the other plate to extend into the keepers on move ment of the plates relative to each other to assume matched relation, said plates having openings to assume registration with each other on the plates assuming matched relation, a spring influenced pinto extend through said openings, and a screw having a. threaded mounting to engage with said pin for moving the pin out of the opening of one of said plates.

2. In a shoe heel construction, a fixed section and a removable section, plates secured to opposed faces of said sections, keepers on one of said plates, tongues on the other plate to engage said keepers,- said plates having openings, a spring influenced pin to extend through the openings of the plates and an operating means carried by one of the sections to engage and move the pin out of the opening of one of said plates.

3. In a shoe heel construction, a fixed section and a removable section, plates secured to opposed faces of said sections, keepers on one of said plates, tongues on the other plate to engage said keepers, said plates having openings, a spring influenced pin to extend through the openings of the plates, a nut mounted in the removable section, a screw threaded in the nut to engage the pin for moving the latter out of the openings of one of the plates.
